Abstract
The invention relates to a calcination method for lithionite and industrial waste slag, and relates to the technical field of lithionite calcination. The method comprises steps of mixing the lithionite and the industrial waste slag according to a weight ratio of 1:1-5; adding a proper amount of water into the material mixture; grinding uniformly in a ball mill; filtering, by a filter press, ore pulp obtained by concentrating the ball mill pulp; sending filter slag of the filter press back into a rotary kiln and performing high-temperature calcination at 700-1200 DEG C, wherein Li+ in the molten mass of the lithionite and SO4<2-> in the industrial waste slag are reacted to produce Li2SO4 during the high-temperature calcination of the lithionite and the industrial waste slag at high temperature; and cooling, and crushing by a crusher; and adding washing water and grinding with water to a technology required granularity. According to the method, the industrial waste slag is used as the main auxiliary material, thus achieving comprehensive utilization of the slag, utilizing the thermal energy comprehensively, increasing the production efficiency and achieving objectives of reducing energy consumption and guaranteeing the quality of the calcination material.
